After playing a few games on structured PvP, I began to wonder if there is any way to improve your PvP gear you receive when you join the Heart of the mists.
When you get into sPvP you receive a full-set of abilities, trait points and gear, I see you can change the runes from your gear and one acessory, but I don't see any gear progression as your glory rank passes. So, how does this work?
